Ignition timing hole.

[Fernando Mendes]

It is above number 6 cylinder,it has a small plug that should be removed to check the position of the piston,for example to re-install the distributor.Would like to see a pic or book showing this.Thanks.

Excuse me,but this tool is fited in the head ignition timing hole that Don shown for us?What does the numbers in the circle means in this tool?Thanks.

The scale on the indicator is in thousandths of an inch and used to find piston position reading -say .004" BTC or .004 ATC (before or After Top dead center. The .004 number would be found in the Shop service manual. This is definately an "old school" way to time the old flatheads. I would use a timing light always over this timing tool. The tool is good to locate exact TDC. To me other than that it is just a great old tool old tool!
